Finally I figured out the problem! Things are:
1- What are specified in the command as ADDRESS and PORT
java -jar indexdata.jar result hdfs://ADDRESS:PORT/data-Index
must be the same things as fs.default.name<property>

So, having <value>hdfs://hostname:9000</value> and running hdfs://localhost:54310
fails to work (ipc.clinet time out). Even the hadoop report command says namenode is up because
it read the fs.default.name

2- After matching ADDRESS and PORT, I got this errorException in thread "main" java.lang.NullPointerException
        at IndexHDFS.indexData(IndexHDFS.java:92)
        at IndexHDFS.main(IndexHDFS.java:72)

The problem here is that the destination folder hdfs://hostname:9000/data-Index doesn't exist
and the reason is that when I used copyfromlocal, I embedded data-index/ into multiple folders
(my script did that though!). So the correct form is hdfs://hostname:9000/path/to/data-Index

Now it is fine.Thanks to Sandeep for motivating me for focusing on the address and port.
